Some of you might be interested in this video. Shows how the response time works when you are monitoring the output of the Dawn RFX down pressure system with a Seedstar or 20/20. Effectively gives you ability to react in real time.

One thing I have been hearing again and again this spring, especially on large toolbars, is that you are getting a huge amount of down pressure variation across the width of the frame. This system allows you to run multiple sections and even the GFX row cleaner off of a single remote. You have to have down pressure sensors at the ends of both wings and on the center section at a minimum if you are on a 60 ft or larger planter and especially if it is on 20".
